摘　　要：为了选择冬牧70黑麦收后复种籽粒玉米最佳时期,筛选适合本地复种的籽粒玉米品种,开展了冬牧70黑麦草不同收获期(5月20日、5月30日、6月10日和6月20日)后复种不同积温籽粒玉米品种大田试验。2年试验结果表明:5月30日之前收获冬牧70黑麦后复种的籽粒玉米果实性状较好,产量较高。玉米品种应以先玉335、先正达408、长城706和PR3394为主。In order to select the best period of Dongmu 70 （Secale Cerale） multiple cropping of maize grain in Ningxia, maize grain varieties suitable for local cultivation were screened. After recycled, field test on maize grain at different accumulated temperatures were carried out harvested on May 20, May 30, June 10 and June 20. Two-year experimental study results showed that Dongmu 70 （Secale Cerale） harvested before May 30 and multiple cropping of maize grain had better fruit traits and higher yield. Therefore, it was suggested that the priority be focused on Xianyu 335, Xianzhengda 408, Changcheng 706 and PR3394.
